Rule number one is always “Don’t Panic!”.
As the knowledge of the world increases, fear recedes.
This is especially noticable in video games. When facing a new enemy the fear rises. Once it’s known exactly how it moves and attacks, it is more annoying than frightening.
Interestingly, this doesn’t seem to apply as much to other players in the game, we know they are sometimes just as scared as us, and usually don’t have special abilities.
Know the universe to respect it.
